Acts 12:3-5

ASV(i) 3 And when he saw that it pleased the Jews, he proceeded to seize Peter also. And [those] were the days of unleavened bread. 4 And when he had taken him, he put him in prison, and delivered him to four quaternions of soldiers to guard him; intending after the Passover to bring him forth to the people. 5 Peter therefore was kept in the prison: but prayer was made earnestly of the church unto God for him.
